How to force ADSL modem to connect at maximum speed available? I have a 512kbps internet connection. But most of the time it connects at lower speeds. When it's already connected, even more bandwidth is available, still it stuck at previous speed. I have to unplug the modem and re connect. Only after that the new speed appears. Is there a way to force the modem to connect at 512kbps all the time? I use a USB ADSL Modem. ADSL Router users doesn't have this problem.
